CIGARETTE-PACKAGING MACHINE.

Application ma october 17; 1925. semi no. sacos."

This invention relates to an improved cigarette ackaging machine whichis particularly esigned, adapted, and used, as complementary to, and forpacking the product of, the new standard duplex cigarette machines ofthe industry, although it will of course pack cigarettes made on othermachines. The standard duplex cigarette machines of the industry havecapacities of sixteen hundred cigarettes per minute, by far the greatestoutput known. To take care of this great manufacturing out ut, thepresent machine is designed, adapte and used,'for packaging sixteenhundred cigarettes er minute, in eighty packages, each containing twentycigarettes. This is by far the greatest packaging output known. By theuse of such machines, in place of those'of less than one-half of theircapacity which were heretofore of necessity employed, the capacity ofcigarette factories is greatly increased, without additional investmentin enlarged or new buildings; the overhead expenses of existingfactories are decreased; the number of requisite machines, machineoperators, inspectors, and mechanics, is decreased; better cigarettes,because less handled, are produced; and said cigarettes are produced atdecreased cost. The main o'bject of the present invention is, therefore,the production of a cigarette packaging machine of this high capacity,and aiding in effecting these desirable results. But the productivespeed is so high 4that the old way of compacting the cigarettes, inorder to prepare them for wrapping, is unsuitable; the old way ofwrapping the compacted cigarettes, is unsuitable; and the old way ofsealing the wrapped cigarettes, or drying the paste employed on thewrappers, is unsuitable. Further objects of the invention, therefore,are the production of means for compacting the groups or collocations ofcigarettes progressively, step by step, with brief pauses inthecompasting action between steps in order -to give lthe tobacco time toadjust itself to its closer quarters without losing its life orresiliency; the production of improved means for wrapping thecollocations-of cigarettes; and the production of improved means forsealing vthe packages or drying the paste employed. With these and otherobjects not specifically mentioned in view. the invention consists incertain constructions and combinations which will vbe hereinafter fullydescribed hereunto appended.

In the accompanyin drawings, which form a part of this speci cation andin which like characters of reference indicate thel same or like parts,Fig. 1 is a plan view of a maand then specifically set Aforth in theclaims chine constructed in accordance with the in'- vention, andshowing the arrangement of the several units; Fig. 2 is a plan view Vofthe actuatin parts, below the bed plate; Fig. 3 is a ront elevation ofthe cigarette hopper which supports a mass of cigarettes to be operatedupon; Fig. 4 is a front elevation of the compacting means; Fig. 5 is asectional side elevation of the compacting means; Fig. 6 is a detail ofthe compacter gear adjuster; Fig. 7 is a side elevation of the labelfeed, label wrapper, and, stacker; Fig. 7a is a side elevation' of thetinfoil feeding and wrapping devices; and it also shows the hopper,compacter and actuating parts; Fig. 8 is a detail view ofthe tinfoilfeed roller disengaging device.

U In carrying the invention into effect, there 1s provided means forseparating loose co1- paper to each collocation of cigarettes, and

improved means for stacking or holding the y wrapped collocations untilthe adhesive employed has had timeto dry. These various .means and partsmay be widely varied in construction wit-hin the scope of the claims,for the particular machine selected to illustrate the invention is butone of many possible concrete embodiments `of the same. The invention,therefore, is not to be restricted to the specific construction shownand described.

Referring to the drawings: The cigarettes to be packed are placed in asuitable receptacle on the machine by an attendant who replenishes thesupply from time totime. vThe packing capacity of the present machinebeing equal to the manufacturingr capacity of the standard duplexcigarette machine in connection with which it is designed to be used,the cigarettes to be packed may be inspected and transferred directlyfrom the cigarette making machine to the present cigarette packingmachine, thus effecting a saving vin storage space, eliminatingunessential handling, and resulting in packagingbefore the tobacco inthe cigarettes dries out and becomes brittle. Such a receptacle is thehopper marked 30. This hopper is provided with hinged agitator plates 31of well "known construction and operation. The bottom of the hopperopens into two downwardly diverging ducts 32. A removable andtransparent plate 33 rests against the otherwise open front of thehopper 3C. This plate serves to keep the cigarettes in proper positionin the hopper and to permit ready inspection of their progress. Byremoving the plate 33, all of the cigarettes in the hopper become atonce accessible, so that a defective cigarette may be removed, or anaccidentally misplaced cigarette may be straightened out.

The agitator plates 31 (Fig. 3) are connected by arms 34, rod 35,bellcrank 36, and pushrod 37, to the lever 38. This lever is pivoted ona shaft 39, and it carries a cam bowl 40 engaging an open cam 41 on acam shaft 42, the latter being driven from the shaft 215 by the gears216 and 218 (Fig. 2). A coil spring 43 (Fig.`3), which is int-erposedbetween the bed plate 47 and a collar 44 on the pushrod 37 keeps the cambowl 40 in contact with its cam. The agitator plates 31 can be stoppedwhile thel machine is running, if desired, by forcing the pushrod 37down and slipping the hinged latch 45 over a pin 46 on thc collar 44,which results in throwing the cam bowl 4Q out of engagement With its cam41.

As the cigarettes are shaken down into the diverging ducts 32 theybecome, in each duct, arranged in three row's with staggered centres, bymeans of the partitions 364 and stop 365, the centre stops beingone-half the thickness of a cigarette higher than the end stops.

Loose collocations of cigarettes are alternately separated from the massin the hopper 30 and ducts 32, and alternately delivered to compactingmeans. In the specific machine shown and described, each collocationcontains twenty cigarettes. The separation of the collocations from themass is effected as follows: Enough cigarettes for one collocation andone package are pushed out from each of the ducts 32 by plates 49(Fig. 1) carried by aplunger 50, these plates being made of a height toengage seven cigarettes in the end rows and six cigarettes in the middlerow of each duct 32. There are of course two `of these .plungers, andthey come into operation alternately, so that although the productivespeed of themachine is high, the operating speed of each plungermechanism is relatively low; ,and excessive wear and tear is avoided.The plungers 50 run on guide rods 51 which are fastened to clampbrackets 52`and 53 bolted to the bed plate 47. The plungers are actuatedby levers 54 (Fig. `7) pivoted on the shaft 55, and connected to them bythe rods 94. The levers 54 carry cam bowls 170 tracking on cams 56 onthe shaft 57. The cam bowls are held to their duty by long springs 58con-l nectingr the levers 54 with` the rear frame 48 (Fig. 2). ,Theshaft 57 is driven from the main shaft 215 bymeans of the gears 217 and219. While the machine is running,

'either one, or both, of the plungers can be stopped by hooking thelatch 59 (Fig. 71), pivoted to the side of the hopper frame, over thepin 60 of the plunger 50. The latches 59 are fastened to the hopperframe 111 by springs 112 which are so positioned with relation to thepivots 171l that the latches are locked in place at both of theirextreme positions.

The plates 49 force the collocationsof cigarettes from the ducts 32directly int-o the range of action ofthe compacting` means whichprepares them to be vvrapped.-l This compacting means includes an outerrotor 62 (Figs. 4 and 5), an inner rotor 63, and the cam 64. The outerrotor, with its hub 65,

integral part of a'stationary shaft 67, and

has the arms 68 provided withl the top plates 69. It is secured inposition by the end plate Aloo lin

rotates around an eccentric 66, forming an 78 which is held to the endof the eccentric 66 by the screw 79. The inner rotor 63, with its hub70, rotates around the shaft 67 which is supported by the pedestal92,(Figs. 1 and 7a). The cam 64, between the outer and inner rotors,rotates around the eccentric 73 which is also integral with thestationary shaft 67. The arms 72 of the inner rotor have bosses 74 inwhich slide rods 75 fitted with the plates 76. Coil springs 77, attachedto the plate 76 and to the arms of the inner and outer rotor, keep thesliding rods `7 5 in engagement with the cam 64.

The driving gear 80 of the outer rotor has bosses 82 abutting the hubarms 83 of the outer rot-or 62 and secured thereto by the bolts 84.These bosses 82 pass through the openings 85 of the cam 64 which provideenough clearance to permit a limited but free reciprocating motion. Thegear 81 of equal diameter and pitch as the gear 80, mounted rotatably onthe hub 70 of the rotor 63, has screws 86 (Fig. 6) 'bearing against thelug 87 of the hub 70. By slacking one screw and tightening the other,the

angular relation of the walls of the compactor can be regulated. Bothgears 80 and 81 mesh with a pinion 88 keyed to the shaftA 89 which issupported in bearings 90 and 91 of the pedestals 92 and 93 respectively(Fig. 1). It will now be understood that the compacting means includes aseries of expanding and contracting collocation pockets having movablewalls.

The amount of eccentricity of the eccentrics 66 and 73 is governed bythe required size of the finished package in relation to the number anddiameter of the cigarettes prior to compacting. When the rotors and camrevolve around the stationary shaft 67 and its eccentrics, there isproduced a relative reciprocating motion of the rotor 62 and cani 64 asthey rot-ate on different centers. The eccentric 66 regulates the amountof expansion and contraction, between the walls of the rotors, whichdetermines the ultimate thickness of the package; The eccentric 73regulates the amount of expansion and contraction, between plates 69 and76, which determines the ultimate width of the package. The componentparts o-f the compactor are so arranged that maximum expansion prevailsin the pockets at which the collocations of cigarettes enter from thehopper, and the collocations are ejected from the compactor aftermaximum contraction has taken place and after the pocket walls haveagain opened part of the way to relieve all pressure on'the collocationat. the moment of ejection.

The compactor rotates in the direction of the arrow shown at the left inFig. 4, its

motion bein'g made intermittent by the aid of'the indexing device to behereinafter described, and the expansion is maximum at 95 and thecontraction is maximum. at 96. The collocations of cigarettes areintroduced at 97, on either side of 95, and are expelled at 98, half waybetween 96 and 95.

The cigarettes entering the compactor at 97 are stopped by plates 344mounted on blocks 345 which are pivoted on pins 346 of brackets 347.These vbrackets 347 are fastened to the bed plate of the machine, andthey have pivoted latches 348, with set screws 349, for keeping theplates 344 in position. By lift-ing the latches, the plates 344 can beswung out and away from the compactor to facilitate the cleaning of thecompactor pockets.

The step by step movement given to the compactor, and the progressivecompacting action developed by the rotors and cam during each suchmovement,.results in gradually, though quickly, reducing eachcollocation of cigarettes to its proper condition for being wrapped,without destroying the natural resiliency or life of the tobacco. ,ingto the required degree in one movement, in the extremely limited timeavailable, would have this undesirable effect, particularly upon freshlymade cigarettes.

As soon as a collocation of cigarettes is thus made ready for wrapping,it is pushed cut'of the compactor pocket at 98 int-o mechanism -forwrapping it in tinfoil, by a plunger 99 (Figs. 1 and 7a) which ismounted on a slide 175 sliding on a guide bar 100, the latter beingfastened' to the side of the hopper frame 111. The plunger 99 and slide175 have a link connection 172 with a lever 173 which is pivoted on ashaft 174 and connected by a rod 101 with a bellcrank 102 (Fig. 7), the)latter being pivoted on the fulcrum shaft 103 and engaging a closedcani` 104` (Fig. 2) on the cam shaft 42, through the agency of its cambowl 268.

The compactor and other parts of the machine have intermittent motionobtained by an indexing device on the'shaft 89 (Figs. 17 and 18), andincludingl the disc 105 'which is provided with equally spaced studs106. On the shaft 89, adjacent the disc 105 but separated therefrom bythe boss 107, is an arm 108 carrying pawls 109 and 110 pivoted on pins129. The arin 108 is actuated by an eccentric 113 on the cam shaft 42,through Compactthe agency of a lever and rod 128. The pawls 109 and 1,10grip the stud 106l between stroke of the lever 108, by the action of thespring 118. The lever moves upward until the pawls engage with the nextfollowing stud, the pawl 109 pressing down on the spring and the pawl110 yielding on coming into contact with the stud but being kept inresilient relation therewith by the action of the spring 118. At themoment the downward stroke begins, the stop pin.I 127 is withdrawn fromthe notch 115 by the lever 119, then engaging lugs 120 of the sto-p pin,and connected by a rod 121 with the lever 122 which is pivoted on theshaft 39, and has a'cam bowl 123 engaging an open cam 1241on the shaft42.

The tinfoil which forms the inner wrapper of the packages is from timeto time placed on the reels 130 and 131 (Figs. 1, 9 and 10), the hubs132 and 133 of which are inserted into the sleeve of the revolublesupport 134, and held in pla-ce by the catch levers 135, in conjunctionwith springs 1,36, engaging with grooves 137 on the reel hubs. The reell130 is normally in action, while the reel 131 is a loaded spare reel,always readily available for use in thc event of defective tinfoil, oran exhausted supply on the reel 130. The support 134 rests on the top ofa support 138 which is bolted to the pedestal 92. A lock opening lever139, on the support 138, which engages the notches 140 of thevsupport134,

permits the support 134 to be swung around .1180", thus bringing :thespare reel 131 into the. position of the reel 1.30. A fresh reel 131 canthus be almost instantly substituted ffor an empty reel 130, which canthen be taken off and replaced by a loadedone while the machine isrunnlng. The tinfoil is drawn from the reel 130, over the smoothingwedge ,141, by rollers 142 and 132 around which are looped the guidestrips 350 and 351. which fit grooves 352 and 353 res ectively, andserve as guides for the tin oil, introducing it into the upper guides145 which are supported Aby 4the'bracket 146 from the pedestal 92. Theguides 145 are provided with springstrips 144 which guide-the tinfoilpast the knife gap into the lower guide 155. v a v vThe tinfoil is cutto size by the knife 147 which is resiliently pivoted on the bracket 146b meansl of the pin 148 and spring 149. A 1in 1150 lconnects the knifewith a crank 151 which is pivoted on the shaft 152, and

,'11v and 12) on the sleeve 166 which has a lug 167 and is revolublymounted on a pin 168.

This pin has a hand knob 169` and is turnable in the bracket 354 untilstopped in either direction by either of two Hat sides of the cam ,355abuttin against the ledge 356 of the bracket 354. Fixedly mounted on thepin 168 is a sleeve 358 having a lug 359 which is held in resilientrelation to the lug 167 by the spring 360. The relative position of thelugs can be adjusted b means of the screw 361 which is threaded throughthe lug 359 and abuts the lug 167. This allows the stop plate 165 to beraised or lowered when 75 in position. The coiled spring 362, on the pin168, keeps the cam 355 pressed against the bracket 354, the frictionpreventing the stop plate from bein jarred out of position when in itsworking position. By turning the knob 169, the stop plate can be swungaway from the guide box, allowing the removal of any tinfoil in theguide box after the machine is stopped.

In order to keep the tinfoil stationary while it is being cut, thusinsuring a straight cut, a counter travel ofthe tinfoil, which is equalto the feeding speed, is` periodically obtained by raising the feedrollerarm 161, pivoted on the shaft 156 which has a bearing 90 in thedestal 92, by means of a crankpin 157 (Fig. 28) of the crank 158 on Vtheshaft 159, engaging the guide slot 160 of the arm 161. This imparts anup and down motion to the feed rollers, alternately stopping and 05accelerating the speed of the tinfoil. To facilitate insertion of thetinfoil. between the feed rollers, the roller 143 is made to be movedoutward, b a lever 164 actuating the 'eccentric 162 against theadjustable spring 100 163 which, on releasing the lever, brings theroller back to its normal position.

Each collocation of cigarettes from the compacter ocket 98 is ushed bythe lunger 99 Fi 15 and 16 in between the `105 elts 176 and 1 7 and thehorizontal rollers 178, the tinfoil having been folded len hwise overthe collocation, as shown in ig. 19, by the forward movement of theplunger, the roller 178 effecting the forward tucks 11o vFig. 20). Thefolding plates 180 effect t e preliminary upward folding of the lowerside flaps (Fig. 21), these folds being'.

raccentuated by the pressure of inclined` rollers 181 rotating in thedirection of their 115 respective arrows. The folders 182 and 18,3effect the downward folding of the upper side aps (Fig. 22), these foldsbeing accentuated by the inclined rollers 184 rotating in the samedirection as the rollers 181, but their action is downward and forwardby reason of their more elevated position and inclination opposite tothat of the rollers 181, which act upward and forward. These rollersovercome the tendency of the tinfoil to drag on the folders and becomedisplaced on the collocation of cigarettes during the rapid movement ofthe tinfoil over the folders; and in so doing, they accentuate thefolding action, causing the folded tinfoil to lie smoothly and flatlyagainst the collocation of cigarettes.

The belt 177 runs over its actua-ting drum .193 on the shaft 194 (Fig.7a), over the idler 195 on the bracket 196 rotatably mounted on theshaft 194, then over the uide roller 197, and thence over the top o thelower supporting bracket 200 to the roller 198 and back to the drum 193.The belts 176 and 177 are held taut by the idle rollers through thepulling action of the springs 199. The bracket 191 has a hingedextension 191L which can be swung ig by operating the toggle 179 (Fig. 7facilitate the removal of a package in the event of torn tinfoil orother trouble.

The tinfoil feed and folding mechanism is driven as follows: Thesprocket 201, on the cam shaft 42, drives the sprocket 202 on the beltdrum shaft 194. The sprocket 203, on the same shaft, drives'the, endlesschain 204, which runs over the idler 205, thence over the sprocket 206on the belt drum shaft 187 andpvsprocket 207 on the,shaft 156, thenceover the sprocket 208 on the shaft 209, which shaft has bevel gears 210driving the bevel pinions 185 of the inclined rollers 181 and 184. Theshaft 156, of the tinfoil feed, carries a sprocket 211 which drives thefeed roller 142 through the sprocket 212 and spur gears 303.l On theshaft 156 is also keyed a spur gear 213 meshing with a gear 214 on theshaft 159, the later having a crank 158 which actuates the arm 161 bymeans of a crankpin 157 engaging a block 363 slidable in the guide slotAfter the tinfoil or inner wrapper has been applied to a collocation 'ofcigarettes, the collocation passes directly into the label or outerwrapper applying mechanism which puts the outside wrapper or labelaround the tinfoil wrapper, the labels already cutto size, being fedfrom a magazine 270, into which a supply is stacked from time to time,into the path ofthe package as it leaves the tinfoil folder and entersthe label folder. The tinfoil-wrapped package is propelled from betweenthe belts 176 and 177 into the label folder by the prongs 221 whichswing on pivots 222 on the pieces 223, the latter being slidable on .aguide bar 224. These prongs have cam bowls 225 engaging stationary cams226 which operate to swing the prongs from the dotted-line outwardposition to the full-line inward position (Fig. 15) when the slides 223are moved forward. 'lhe slides 223 are actuated by the levers l22(pivoted on the shaft 228 by a common hub 229 provided with an arm 230connected by the rod 231 with a lever 232 pivoted on a,

beller-ank 233. The lever 232 is oscillated` by a rod 234 connected witha lever 235 fulcrumed on the shaft 103 and having a cam bowl 236engaging a closed cam 237 on the cam shaft 42. At the beginning of thereturn stroke, the prongs, whichv are provided with a slot 238, swinginward, and, reaching over the guide 239, engage the package an impartthe rear tuck to the tinfoil wrapper (Fig. 23). As the paekageenters thelabel folder the label folds itself over it lengthwise (Fig. 24), thefold being insured'by the roller 240 'in the cover plate 241, andimmediately receives the forward tuck through the agency of the tuckers242. rThe package is further propelled over the bottom bars 243 by therack 244 which has an upright pusher plate 245. The rack is retracteddownwardly by rods 246, pivoted on the lever 247, which, through theagency of the gears 248 and 249, turns in unison with, but in oppositerelation to, the bellcrank 233, the latter being actuated by a rod 250which 1s connected with a lever 251 fulcrumed on the shaft 103 andhaving a cam-bowl 252 engaging the closed cam 253. The extreme positionsof the rack are indicated by the dotted lines in Figs. 15 and 16.

The rack propels the package past folders 254 which fold the lower sideflaps upwardly (Fig. 25), the upper side `flaps still projecting andpassing subsequently over paste wheels 255 under thespring guides 256 ofthe paster 257. `In passing the folders 258, which are fastened to thecover plate 241, the upper side flaps of the label are folded downwardlywith their gummed lower rear Hap of the tinfoil wrapper has previouslybeen folded up by the rear push plate of the rack.

The package is then propelled onto la plunger plate 259 which isactuated by a rod 260 sliding in a vertical guide 261 and.

moved up and down b `the lever 262 engaging the lever 263, t e latterbeing connected by a rod 264 to a lever 265 fulcrumed on the shaft 103and actuated by a cam bowl 267 engaging a cam 266 on the shaft 42. Theplungerv 259 pushesthe package upwards into the stackerpast the springs269 which press the packave against the lip of the cover plate 241, thusefectin the folding down of the rear flap4 of the tinfoil wrapper (Fig.27).

The labels are extracted from the magazine 270 by the suction plate 271which grips the leading label by suction, and on each of its downwardstrokes the plate deposits a label between the rollers 272 and 273.'T110.l roler 273 is mounted on a rocking bracket 274, and on its upwardstroke it meets the suction late at the end of the downward swing o thelatter. The downward travel of the roller 273 guides the label into theedges, pressed over the lower flaps (Fig. 26). Thev guide box.275,through which it passes until.

The ends of the magazine are closedby guidestri s 357, the rear guide strips being adjustab e.

The travel of the roller 273 is effected by means of levers 286, 287 and288 on the shaft 289, which shaft passes through the sleeve 281 and isactuated by a/,pushrod 290 connected to a lever 291 on the fulcrum shaftr.103. The lever 291 has a cam bowl 292 engaging a cam 293. The suctionvalve 294 is controlled by a lever 295, on the shaft 289, actuatedthrough a crank 296 by a pushrod 297 connected with a lever 298 on thefulcrum shaft 103. The lever 298 has a cam bowl 299 en aging the cam300.

The label fee roller is driven through the sprocket 301 from thesprocket 302 on the shaft 156, the latter being driven by spur gearsfrom the shaft 159.

The pasters are mounted on the rear pedestal 93 of the machine, eachpaster having a gear 304 mounted on its paste wheel shaft. The gears 304are driven by gears 305 on a shaft 306 extending across the two pastersbelow the package runway. One of the gears 305 is in mesh with gears 307driven by a gear 308 on the shaft 309. This shaft is supported in abearing 366 and is rotated by a sprocket 310 driven from the shaft 194by the sprocket 220.

After the label or outer wrapper has been applied to a package, thelatter is passed on to a stacker wherein it is held long enough to givethe paste time to dry. This stacker includes three endless belts 311,312 and 313, the belt 311 passing over rollers 314 and 315, the belt 312over rollers 316 and 317, and the belt 313 over rollers 318 and 319, allrollers being actuated by the chain 324, 325 and 326, causing the beltsto run in the direction of the arrows in Fig. 14. The nished packageispushed up between the belts 311 and 312 vby theplunger 359 and carriedupward in between the resilient discs 327 which grip the packages 343and carry them around and down in 4between the belts 312 and 313. Theyare then conveyed downwards into the chute 328 which is supported by theIbracket 329. `It will now be understood that these belts form verticalpath- Ways into the bottom of'one of which the packages are introduced,and then the discs voperate at the top of these pathways to .are held innon-slipping contact with their rubber or other suitable material, thesmall end of each nipple being inserted in an aperture 368 of the` plate271 and clamped in place by the grommet 369. This pliable nipple adjustsitself to the varying relative positions of label and suction plate,thereby preventing the label from becoming detached before the operationof transferring the same to the rollers is completed.

In view of the foregoing, a detailed description of the operation of themachine is deemed to be unnecessary, and it is therefore omitted in theinterest of brevity.
